Poorly designed business software is the main time waster for 94% of users, according to an international survey.
The survey of more than 1,000 European and US business IT users found that learning to use new applications and modules was the top time waster.
This was followed by difficulty in searching for relevant information in an application and difficulties resulting from illogical grouping of functionality.
In the UK, 40% of respondents said web applications were intuitive and easy to use compared with only 17% who voted for business applications.
Enterprise applications company IFS, which commissioned the survey, said suppliers should bring elements from consumer websites into the business world.
IFS chief executive, Alastair Sorbie, said embedded application search, integrated communities, enhanced navigation and individualisation were just some of the elements that could boost productivity.
The survey also found that 13% of respondents were frustrated by the time wasted in transferring data between systems and 11% said they wasted time navigating between different applications.
